Here is a better one I think, it is fully self-contained, uses an interval to refresh automatically and provides an output, make a field with whatever name you want.
var text base = URLRoot() & "db/" & Dbid();
var text rdr = "&rdr=" & URLEncode($base & "?a=dr&rid=" & [Record ID#]);
var text url = $base & "?a=API_EditRecord&rid=" & [Record ID#] & "&_fid_15=";
"<div id='rdr' value='"& $rdr &"'/>" &
"<div id='url' value='"& $url&"'/>" &
var text timeScript = "setInterval(function(){var d=new Date(); var cDate = d.toLocaleString().replace(',',''); var eDate = encodeURI(cDate); $('#timeTarget').text('Time ('+cDate+')'); var t= $('#url').attr('value') + eDate + $('#rdr').attr('value'); $('#timeTarget').attr('href',t);},1000);";
var text script = "(function(){"&$timeScript&"})();";
"<img src=' ' onerror=\"javascript: "&$script&" \"></img>"&
"<a id='timeTarget' href ='void' class='Vibrant'>Time</a>"
